[0026] Reference Figure 1 - Figure 2 As shown, a fixing threaded hole is provided in the middle of the mounting plate 8 .
[0027] Specific implementation process: The base 1 serves as the basic supporting structure of the entire device. Its upper end is fixedly connected to the upper cover 9 by bolts to form a relatively closed internal space for accommodating other components. PCBA and radiator: PCBA2 is installed inside the base 1. Multiple radiators 3 are also installed inside the base 1 and are arranged equidistantly. The PCBA will generate heat during operation, and the radiator is responsible for dissipating the heat. Panel and other components: The rear panel 4 is fixedly connected to the inside of the base 1 and is located below the upper cover 9. The front panel 7 is fixed to the front end of the base 1. A pair of symmetrical mounting plates 8 are also fixed in the middle of the front panel 7 for installing other components or connecting to external devices. The position and function of the fan: The fan frame 11 is fixedly connected Connected to the inner front end of the base 1, a plurality of fans are fixedly connected to the middle of the fan frame 11. When the device is running, the fan starts to work and sucks air from the front end of the device. The formation of the air duct: Since the windshield assembly 5 is fixedly connected to the rear end of the base 1, combined with the function of the fan, the air is sucked from the front end of the device, passes through the heat source PCBA of the power module part and the radiator area, and is then guided by the windshield assembly 5 to form an independent air duct. This design changes the situation in the prior art where the fan is in front and the air is discharged at the rear but no independent air duct is formed. The transfer of heat from the PCBA to the radiator: During the operation of the device, the electronic components on the PCBA2 generate heat, and this heat is quickly transferred to the radiator 3 in close contact with it. The heat sink 3 has a large heat dissipation area and good thermal conductivity. Heat can be evenly distributed on the surface of the heat sink. Heat exchange between the heat sink and the air: When the fan drives the air flow to form an air duct, the air flowing through the surface of the heat sink 3 exchanges heat with the heat sink. The air absorbs the heat from the surface of the heat sink and its temperature rises, while the temperature of the heat sink gradually decreases, thereby achieving the purpose of dissipating the heat generated by the PCBA to the surrounding environment. Assembly start: The assembly process first places the base 1 on the work surface, and then fixes the PCBA2 inside the base 1. Since the heat sink 3 has been fixed on the PCB in advance, the heat sink is also fixed to the corresponding position in the base while fixing the PCBA. Installation of the fan and windshield assembly: Place the fan After fixing it to the fan rack 11, fix the fan rack on the base 1, and then fix the windshield assembly 5. This step is crucial for forming an independent air duct. The vertical installation of the windshield assembly 5 not only provides a good air duct environment for heat dissipation, but also facilitates operation during the production process, and also provides convenience for after-sales maintenance. Installation and arrangement of other components: Process the copper busbar kit 10 and its related components, fix the handle 6 to the front panel 7 and then fix the front panel 7, and then fix the front ears 8 on both sides. After arranging other wires and other components, finally fix the upper cover 9 to complete the assembly of the entire structure. Overall heat dissipation coordination: During the operation of the device, the various components work together, and the fan provides the power for air flow, allowing air to flow in the air duct;The windshield assembly 5 ensures the independence and stability of the air duct, allowing air to flow efficiently through the radiator 3. The radiator 3 transfers the heat generated by the PCBA 2 to the air. The multiple heat dissipation holes in the middle of the front panel 7 help to exhaust the internal hot air, further improving the heat dissipation efficiency. Structural stability and maintenance convenience are coordinated: through a reasonable assembly sequence and the close coordination of various components, the stability of the entire device structure is guaranteed. For example, the bolt connection between the base 1 and the upper cover 9 and the fixed connection between each panel and the base ensure that the device will not loosen or deform during operation. At the same time, the rational layout of various components, such as the arrangement of the mounting plate 8 and the design of the front panel 7 and rear panel 4, make it easy for technicians to inspect, repair, or replace various components during maintenance.
